When AC drive motors or large DC drive motors are used, the customer should ensure that
their motor protection and starting circuits conform to ABYC recommendations or other
applicable local electrical codes. Ensure that the electrical cable used to supply the motor and
control connections are sized properly to prevent unreasonable voltage drop.
The solenoids use a common connection Terminal 5 and can be activated by a positive or a
negative control signal. The port and starboard manifold coils are connected to Terminals 6
and 7 respectively. The high-speed coil is connected between Terminal 5 and 8. The high-
speed coil uses the same polarity control signal as the port and starboard solenoids.
DO NOT
energize the coil detached from the valves. It may cause
them to heat up beyond normal operating temperatures.
